BERLIN, GERMANY - JANUARY 24: Freshly-roasted espresso coffee beans cool under an iPhone with a timer app attached to a refurbished 1918 Probat coffee bean roaster at Bonanza Coffee Roasters on January 24, 2011 in Berlin, Germany. Bonanza founder Kiduk Reus is among a growing number of so-called third wave artisinal coffee bean roasters who are finding a niche market in Europe and the USA for their carefully-crafted and expensive coffee. Reus insists that the cast iron parts, the slow-roasting abilities and hands-on controls of his flame-roasting Probat machine allow him to develop the most flavour from his carefully selected beans.
